I have been a bit busy but I'll check it out when I get a chance.
Update: Can you explain where you are running into issues? I went to Tools -> Add-ons -> Get Add-ons and randomly installed about 5 different extensions. They all installed without problem in 29.4.0.1. Are there specific ones you are having problems with? And are you using the official release or the experimental build?
